Answer 2

hydraulic lift
excavators
hydraulic brakes
hydraulic presses

Question 3

what is the most common hydraulics in cars?

Answer 3

brakes

Question 4

pressure in a hydraulic system is calculated using what law?

Answer 4

Pascals Law

Question 5

what is pascals law?

Answer 5

PA= Force / Area = NMsquared

Question 6

what forms of power is commonly used in the automotive industry

Answer 6

fluid pressure and air power

Question 7

liquids can easily change ______ and are not _______ they can transmit a _____ but cannot withstand _______

Answer 7

shape
compressible
force
tension

Question 8

what is a hydraulic jack ?

Answer 8

a lifting device used to lift heavy loads

Question 9

formula for area of a plunger and ram?

Answer 9

pie×diameter squared
________________________
4

Question 10

to calculate pumping strokes what formula is used?

Answer 10

number of pumping strokes =

volume of ram
_______________________________
volumes of plunger

formula will look like this:

(Pie x Diameter squared/ 4) x length of ram
_____________________________________
(pie x diametersquared/4) x length of plunger stroke

eg: Pie and length of stroke and ram will cancel leaving only the diameters which can be divided to solve

diameter of ram
